The top part of this dialog shows the first several records from the gains file. This file contains two columns: one with scale factors, and another with the corresponding channel numbers. The purpose of the scale factors is to boost the signal from each channel, especially in the shortwave-infrared spectrum where the solar irradiance signal is much lower. This results in higher levels of radiance. In this particular file, Bands 1-110 have a scale factor of 300, Bands
111-160 have a scale factor of 600, and Bands 161-224 have a scale factor of
1200. When each spectrum is divided by the factors in this file, the 16-bit integers will be converted to radiance in units of
